We present a sustainable one-pot, copper-catalyzed synthesis of 2-phenyl-2H-chromenes with excellent regioselectivity, requiring only a 0.5 mol% catalyst.
A new strategy for the construction of a chiral 4-alkoxy-4H-chromene skeleton was reported. A series of chiral 4-alkoxy-4H-chromenes containing the trifluoromethyl group were obtained in good yields and excellent enantioselectivity.
This research developed a new nanocatalyst by incorporating nanocopper iodide onto the surface of modified layered double hydroxides.
Chromeno[4,3-b]chromenes are synthesized by TiO2/CuWO4. The results highlighted this heterojunction material in photocatalytic synthesis.
Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer, and the limited therapeutic options show poor efficacy in patients, associated to severe side effects and development of resistance.
